Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

We have enough minable nuclear fuel to sustain our current power needs for a couple billion years. And with enough technological gains, we can extend that to well past the time that the sun has died. Hence, it is safe to consider it renewable.
Doesn't invalidate your point, but I just wanted to point this nugget of info out.
Each uranium rod has a life of around 6 years before needing replacement, the relative abudance of uranium-235 is about 0.9% compared to uranium 238 which has 98℅
Sure, the decay chain of uranium 235 is long, but the usability of in converting it to nuclear power the uranium rods last 6 years, not billions.
Even if we take all our uranium-235 reserves (which is about 56,304 kilo-tonnes of uranium-235)
1.) It's unrealistic because we use U-235 for other things 2.) This is a global reserve. Countries haven't made peace with another yet.
I know niche points, i'll admit I really dug through the barrel with this one. Nuclear power plants are also quite expensive to maintain and build since these are often built based on the selected site. Also very inefficient as each reaction loses 1.4 neutrons (or else kaboom).
These reasons are why (despite it generating 17℅ of the US electricity with only 92 reactors), countries don't invest more into nuclear power. Inefficiency + large costs make it unappealing compared to wind which generates 40℅ or even 60℅ (with offshore) of the energy the wind pushes.
